''Puntius bimaculatus'' is a species of ray-finned fish in the genus Puntius. It is found in India and Sri Lanka. It was identified and classified by Pieter Bleeker in 1863. It is commonly known as redside barb'' or two spot barb''. == Description == ''Puntius bimaculatus'' is a small fish with a slender, compressed, torpedo-shaped body. The adult size for both the sexes is maximum 7 cm. This species exhibits sexual dimorphism, which allows for easy identification of the sexes. It has two black spots: one at the base of the dorsal fin and one at the junction of body and caudal fin. There is a colored band from its eyes to the spot at the caudal fin. In mature males, the band has a distinct dark read coloration in the middle with a bronze-greenish-colored stripe above the red band. The eyes have a red-colored outer semi-circle. In females, the red is less pronounced and the bronze-colored band will be difficult to distinguish from its body scale color. The females has a slightly plumper body.
